The Arecibo Observatory is the world's largest reflector of any kind, and has been so for the past 40 years. Originally built for studies of the ionosphere, the Arecibo Observatory has since made significant contributions to planetary studies and astronomy, including the Nobel prize- winning work confirming the existence of gravitational waves. A number of upgrades have improved performance over the years. The most recent has been the installation of a seven-pixel spectroscopic radio camera called the Arecibo L-Band Feed Array (ALFA). I will give a brief overview of the history of Arecibo, and describe in detail the ALFA receiver system and some of its recent results
